Mac is dragging and Safari is slow after OS X Yosemite install

Wow! I just downloaded OS X Yosemite for my Macbook Air and I can tell a difference right away: my Mac is dragging and Safari is going slow as well. When I switch screens with three fingers you can see right away that my Mac became slower.  Also, opening to Full View is also dragging. Why is this?!?! I am pretty sure it is because I downloaded OS X Yosemite I hope there will be an update soon that has fixed this bug!!! A slow Mac is completely annoying. I loved the way everything was completely smooth with OS X Mavericks. I should not have updated my Mac. The display looks horrible anyways.

Hi ..
Not enough free storage space can slow your Mac down.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
For Safari, delete the cache.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.

    ipad 4 retina display is slow after iOS 8, also upgrade to iOS 8.0.1 i think and safari is slow, animations are slow, and i can't restore it to iOS 7, there it was great. i mean its like my iphone 4 with iOS 7 in its best days. i hope no to get stuck again, i mean please let me go to the iOS 7)).

    Upgraded my ipad4 from ios6 to iOS 8 because the new WSJ app required it. HUGE MISTAKE!!!!!!! I can maybe understand some apps being slower but not Safari or Chrome. Apple must be throttling back the ipad4 processor even more with ios8 to force an upgrade to the next gen iPad whenever it arrives.

  • I have a brand new iphone 4. facebook and safari are slow. Is this the settings or the does the phone have a problem?

    I just bought an iphone 4 about 2 weeks ago. the facebook application and safari run slow. I've deleted facebook and downloaded it again. Its a brand new phone so i'm not sure if i have the settings wrong or if theres something wrong with the phone?

    it's not my internet connection. I used facebook and safari with my data services.

  • My macbook is running slow after upgrading to yosemite

    Other's have posted similar experiences by when I ran etrecheck I didn't get a bunch of fails and yet my computer is extremely sluggish since moving from snow leopard to Yosemite.  So much so, that I'm considering going back.  Programs load slowly and switching between programs has a delayed response. Reminds me of the PC I had before I bought my macbook in 2008.
    Any ideas on what might be causing the slow down?

  • HT6346 New iMac very slow after upgrading to Yosemite...

    I recently purchased a 21.5 inch iMac and had it specced up. I was very happy with it until last week when I upgraded it to Yosemite. It has slowed down significantly. When switching between programmes and selecting different actions, it appears to stop, then the "thinking wheel" appears, before carrying out the requested command. Sometimes as much as 10 seconds. For example: the simple act of hitting "reply" in mail, it takes as much a s10 seconds to open a reply mail. I videoed it several times. Very disappointed...
    Specs
    iMac (21.5-inch, Late 2013)
    3.1 GHz Intel Core i7
    16 GB 1600 MHz DDR3
    NVIDIA GeForce GT 750M 1024 MB
    just the process of copying and pasting the specs from About this Mac, took ages. Each line "thought" about it for several seconds before allowing me to select it.

    Similar problem here too (quite high spec 2011 iMac 27") ; takes longer to boot up and Safari is slower under Yosemite than Mavericks.I  have just installed Firefox and had a play around with it and it is much faster than safari ~ just couldn't get the appearance the way I liked so uninstalled. This morning I was using a five year old Compaq (averagely specced) and using Chrome it was much much faster than Safari is currently. I like Apple products (and just bought a new iPod classic for spare ) have, iPad etc but these 'upgrades' are like puling teeth for me. IOS 8 was useless on iPad 2 but improved slightly yesterday with IOS 8.1. I have little interest in technology as an end in itself, ( hifi and audio is my thing) just wanting it to work. I still can't send emails since Yosemite was installed last week as 'smtp servers are offline' ~ well, no they're not as email still works on iPad, android phones and compaq using the same servers.  This really irritates. I was so impressed with iPad 2 when I got it ~ it set itself up virtually and I was sold on Apple's ease of use but I don't get back the 3 hours I spent last Friday checking settings, deleting accounts, re-adding email  accounts and ultimately failing to fix it.
    Yesterday I went to a famous dept store here in the UK to get an iPad mini with retina display as our iPad 2 is 3 years old  but I left the store without buying it; just got sidetracked by looking at Samsung and believe it or not, Surface 3 program microsoft. Enough doubt in my mind after IOS7/8 and now Yosemite.
    I still think Apple's products are beautifully designed and aesthetically and ergonomically impressive, but the Yosemite experience is draining; everyone glad handing about how great it is and it patently isn't. The design changes in the mac mini (lower performance than 2012 model ) and iMac (5K screen notwithstanding, much more difficult to make internal changes)) looks like arrogance.
    Sorry for the negative rant but that's almost certainly me done

    If the "it" refers to a compressed (zipped) spreadsheet that you downloaded, the ".ods" extension is used by LibreOffice and probably OpenOffice (which are free versions of MS Office) for spreadsheets, which would suggest that wherever you're getting that "Excel" file from has switched to one of those programs. I've tried opening an .ods file from LibreOffice using MS Office 2013 for Windows and it does open though with a warning that some things have been changed. I don't know if Office for Mac can normally open .ods files. But if your need is to just open .ods files, take a look at LibreOffice.

  • Why is my macbook pro running slow after os x yosemite upgrade

    Why is my macbook pro running so slow after os x yosemite upgrade

    Please describe the problem in as much relevant detail as possible. The better your description, the better the chance of a solution.
    For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What other changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

  • Why is my safari running slow after updating my mac?

    My safari is running slow after completing a software update.  I have cleared the cache.  It did not help.

    Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
    Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
    If your browser is Safari, then from the Safari menu bar, select
    Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. Any change?
    If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
    Stop plug-ins to save power
    Any change?
    Quit and relaunch the browser. Any change?
    Log out and log back in. Any change?
    Enable Private Browsing in the Safari menu. Any change?
    Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
    If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
    If Parental Controls is active for any user, please turn it off and test. Any change?
    If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
    Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
    Are there any other devices on the same network that can browse the Web, and are they affected?
    If you can test Safari on another network, is it the same there?
    If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

  • Drag and drop support freeze after OSX 10.9.4 update...

    Try relaunch finder or any desktop view option...none working. 
    Upon restart...its back to normal...BUT of only a few minutes!!!! then same issue again....
    Any idea how to fix this BUG please???
    Am using a Mac Pro Quad-Core Intel Xeon

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • No Sound, Safari Slow & MacBook Pro Very Slow after upgrading to Yosemite.

    Hi All,
    Upgrading to Yosemite has resulted in the following issues with my computer/laptop:
    1. I have lost all sound and the sound options are no longer there after looking in Preferences.
    2. Safari only loads parts of pages and then takes forever to load the rest.
    3. Generally the computer has been slow with processes taking over the CPU and there seems to be a lot of hard memory swaps.
    Attached is the EtreCheck.    Any help would be appreciated.   It appears that I also am missing some daemons that are launching.

  • Mac Mini (Mid-2011 Core i7) Slow after Yosemite Upgrade

    I've searched the other "slow after Yosemite upgrade" threads but those seem to relate to Core Duo 2 machines with less RAM.  I have a Core i7 MM w/ 8GB of RAM, after the Yosemite upgrade it constantly lags, I can barely type on it these days because the text lags so badly.  It's unusable to say the least.  Is there anything I can do to speed it up?  There must be a reason why the performance is so bad.

    When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.  
    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    The title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.
    Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
    Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
    Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
    Please don't indiscriminately dump thousands of lines from the log into this discussion.
    Please don't post screenshots of log messages—post the text.

  • Mac OS 10.6.7 Server, Safari Keeps Crashing (after failed FileMaker Server install)

    Mac OS 10.6.7 Server
    After several attempts of installing, uninstalling FileMaker Server 11.
    (FileMaker Server 11 still will not launch, Admin Console)
    Now totally un-installed
    Safari constantly crashes a few minutes after launch.

    I think it is due to the Java update that either comes with 10.6.7 or was released just before 10.6.7 so is probably included in the 10.6.7 update anyway
    Try this
    Open Java Preferences (use spotlight to find it)
    Check what version of Java your computer is using for both the options it should be "Java SE 6 64bit" at the top of both lists  click it and then click options and what is the version number 1.6.0_15, 64bit (this version works)
    if you have version 1.6.0_24 i have found it wont work
    I had this happen with 10.6.6 with the java update and ended up reinstalling the whole server as i thought it was something else causing the problem I have since not installed the java update from reading some info on the filemaker site and then still haven't installed 10.6.7 in case.
    Not sure how you can backdate the java version perhaps check the sun website (or is it oracle now) to see if you can install an older version
    Whatever version is at the top of the list will be used so if you can drag an older version to the top and then restart you should be fine.

  • FF Mac Desktop Addon and links download errors after upgrade to 35.0.1

    My problem started when FF was repeatedly trying to automatically upgrade to 35.0.1. It repeatedly failed the incremental upgrade and said I should download from Mozilla.org. However, after doing that and installing 35.0.1 both addons and application support for links were broken and did not work. I have tried various solutions including deleting mimeTypes.rdf, deleting FireFox and all associated settings using AppZapper. A clean install of FireFox still is having the problem.
    When I try to add any addon, such as AdBlock, I see the message "There was an error downloading" as in the attached image.
    https://support.cdn.mozilla.net/media/uploads/images/2015-02-07-07-12-42-8eb8ad.png
    Similarly if I click on any link which would download a file, it always fails as in the following image where I attempted to download FireFox.
    https://support.cdn.mozilla.net/media/uploads/images/2015-02-07-07-19-04-eb8857.png
    However, if I click on the download retry widget next to the failed download it will succeed as in the attached image.
    These issues first arose after FireFox could not upgrade itself and I did a manual download and install of 35.0.1. Initially, I could not cleanly quit FireFox. It always aborted when I selected Quit. However, since my AppZap delete and reinstall it does quit cleanly. Although, I can not seem to get Addons and link support to work. With out Adblock I really can not use FireFox.
    I also use Chrome and Safari. Those are behaving normally. I also used Disk Utility to repair permissions. Nothing was listed in any directory associated with FireFox.
    Any suggestions as to how to correct?

    <blockquote>
    Sounds like a permissions issue. If firefox can not save things to your hard drive, it won't be able to download things. Have you tried completely uninstalling and reinstalling firefox? That can fix issues caused by update problems.
    </blockquote>
    I have checked permissions, using both Mac OS X tools, and terminal to assure directory was one to which it could write. I have tried to install a fresh clean copy several times without any improvement.

    <blockquote>
    You can fix Adblock Plus by setting this in about:config:
    * dom.indexedDB.enabled -> true
    You could try downloading Firefox from
    * https://www.mozilla.org/en-US/firefox/all/
    </blockquote>
    dom.indexedDB.enabled was already set to true. New installs do not clear the problem
